Hooking Up the System
Overview
Use either the INPUT 1 jack or the INPUT 2 terminals
of the woofer when you connect the amplifier.
• If your amplifier has one of the following types of
output jacks, connect the INPUT 1 jack and the
amplifier's jack using the supplied audio connecting
cord.
— MONO OUT jack
— MIX OUT jack
— SUB WOOFER output jack(s)
— SUPER WOOFER output jack(s)
• If your amplifier does not have the above mentioned
output jacks, connect the speaker terminals of the
amplifier to the INPUT 2 terminals instead.
Note
Use either INPUT 1 or INPUT 2 for the connection. Using
both may result in a malfunction.
Before you get started
• Turn off the power of the amplifier and the woofer
before making any connection.
• Use the audio connecting cords that are supplied to
the respective equipment. If there are not enough
audio connecting cords to make the necessary
connections, you need to purchase some optional
audio connecting cords.
• Be sure to make connections firmly to avoid noise.
• Connect the AC power cord from the woofer to a
wall outlet.
• You cannot connect the CENTER output jack for use
with Dolby Pro Logic function to the woofer. Bass
sound is not output with some Dolby Pro Logic
modes.

Unpacking
Check that you received the following items:
• Audio connecting cord (1)
• Speaker cord (2)
Installation
Install the woofer wherever you like because with the
bass sound range reproduced from the woofer (below
150 Hz), human hearing cannot detect the direction
and position in which the sound is being produced.
Also, since the feeling of stereo is lost with bass
frequencies, a single woofer is enough for reproducing
the bass of stereo channels.
To obtain a better bass reproduction, we recommend
that you install the woofer on a solid floor where
resonance is unlikely to occur.
Notes
• Always install the woofer vertically, keeping a few
centimeters from away the wall.
• Do not place an object on the woofer or sit on it.
• If the woofer is installed in the center of a room, the bass
could be extreamely weakened. This is due to the
influence of the standing wave of the room. If this
happened, move the woofer away from the center of a
room or eliminate the cause of the standing wave, by
installing a bookshelf on the wall, etc.

Getting Started
Connecting to an amplifier with a special
jack for a super woofer
If your amplifier has a special jack for a super woofer
(like a MONO OUT jack, MIX OUT jack, SUB
WOOFER jack or SUPER WOOFER jack), connect the
INPUT 1 jack of the woofer to one of those jacks.
What cords will I need?
Audio connecting cord (supplied) (1)
Hookups
Connect the INPUT 1 jack of the woofer to one of
special jack of the amplifier with the supplied audio
connecting cord.
Note
If the output level of your amplifier is not large enough, the
sound may not be loud enough. In this case, connect the
speaker terminals of the amplifier directly to the INPUT2
terminals of the woofer.
Setting the VOLTAGE SELECTOR
Check that the VOLTAGE SELECTOR on the rear
panel of the deck is set to the local power line voltage.
If not, set the selector to the correct position using a
screwdriver before connecting the AC power cord to a
wall outlet.
Connecting the AC power cord
Connect the AC power cord from the woofer and from
your amplifier to a wall outlet.

Connecting to an amplifier with a single set
of speaker terminals
If your amplifier is equipped with a single set of
speaker terminals, connect the woofer to the amplifier,
and then connect the front speakers to the woofer.
What cords will I need?
Speaker cord (supplied) (1 for each speaker)
Twist the stripped ends of the cord about 2/3 inch (15 mm).
Be sure to match the speaker cord to the appropriate
terminal on the componentes: + to + and – to –. If the cords
are reversed, the sound will be distorted and will lack bass.
It is useful to decide that the speaker cord marked with a
line is always the positive (+) and should be connected to the
positive (+) terminal to avoid any improper connections.
Hookups
1 Connect the woofer to the amplifier.
Connect the INPUT 2 terminals of the woofer to
the amplifier’s speaker terminals with the speaker
cords. Be sure to connect both L and R channels.

terminals, connect both the woofer and the front
speakers to the amplifier.
What cords will I need?
Speaker cord (supplied) (1 for each speaker)
Twist the stripped ends of the cord about 2/3 inch (15 mm).
Hookups
1 Connect the front speakers to the amplifier.
Connect the speakers to your amplifier’s speaker
terminals (A).
2 Connect the woofer to the amplifier.
Connect the INPUT 2 terminals of the woofer to
the amplifier’s speaker terminals (B) using
speaker cords (supplied).

Adjusting the Sound
You can adjust the woofer to suit the sound of your front speakers.
Reinforcing the bass sound gives you a greater sense of atmosphere.
1
Play your favorite song.
Male vocal tunes containing bass sounds are most suitable for
adjustment. Turn the volume for front speakers to the same level as
usual.
2
Adjust the volume level of the woofer.
Turn the LEVEL control so that you can hear the bass sound a little
more than before. To increase the volume, turn the control clockwise.
To decrease the volume, turn the control counterclockwise.
3
Adjust the cut-off frequency.
Turn the CUT OFF FREQ control, depending on the reproduction
frequencies of your front speakers.
Refer to the following when adjusting.
Typical very small sized speakers 1
Typical small sized speakers 2
Typical medium sized speakers 3
Typical large sized speakers 4
4
Select the phase polarity.
Use PHASE to select the phase polarity. Depressing PHASE reverses
the polarity and may provide better bass reproduction in certain
listening environments (depending on the type of front speakers, the
position of the woofer and the adjustment of the cut-off frequency). It
may also change the expanse and tightness of sound, and effect the
feeling of sound field. Select the setting that provides the sound you
prefer when listening in your normal listening position.
5
Repeat steps 2 to 4 to adjust for your preference.
Once you have adjusted the woofer to the settings you desire, use the
VOLUME control on the amplifier to adjust the volume of the woofer
with that of the other speakers. You don’t need to adjust the woofer
settings when you change the volume level of the amplifier.

Precautions
On safety
• Before operating the woofer, be sure that the operating
voltage of your woofer is identical with that of your local
power supply.
• Unplug the woofer from the wall outlet if it is not to be
used for an extended period of time. To disconnect the
cord, pull the cord by grasping the plug. Never pull the
cord itself.
• Should any liquid or solid object fall into the woofer,
unplug the woofer and have the woofer checked by
qualified personnel before operating it any further.
• AC power cord must be changed only at the qualified
service shop.
When turning on or off an amplifier or other equipment
Lower the volume of the amplifier to minimum.
To avoid damaging the woofer
• Be careful in setting the volume control of the amplifier to
avoid an excessive input power.
• Do not attempt to open the enclosuer or remold speaker
units and networks.
• The grill net is not removable. Do not remove it.
In case color irregularity is observed on the nearby TV
screen
With the magnetically shielded type of the speaker system,
the speakers can be installed near a TV set. However, color
irregularity may still be observed on the TV screen
depending on the type of your TV set.
If color irregularity is observed...
nTurn off the TV set once, then turn it on after 15 to 30
minutes.
If color irregularity is observed again...
nPlace the speakers further apart from the TV set.
When howling occurs
Relocate the speaker or turn down the volume of the
amplifier.
On installation
• Do not install the woofer near heat sources such as
radiators or air ducts, or in a place subject to direct
sunlight, excessive dust, mechanical vibration or shock.
• Good ventilation is essential to prevent internal heat
build-up in the woofer. Place the woofer in a location
with adequate air circulation. Do not place the woofer on
a soft surface or too close to a wall as this may obstruct the
ventilation hole on the back.
On cleaning the cabinet
Clean the cabinet with a soft cloth lightly moistened with
water. Do not use any type of abrasive pad, scouring
powder or solvent such as alcohol or benzine.
If you have any questions or problems concerning your
woofer that is not covered in this manual, please
consult your nearest Sony dealer.
